Tendinosis, which is a series of microtears in the

Soreness or pain felt on the outside
(lateral) part of the elbow may be
tennis elbow (lateral epicondylitis). This is the most
common type of
tendinopathy that affects the elbow and most often is
caused by overuse of the forearm muscles. This overuse may occur during sports,
such as tennis, swimming, golf, and sports involving throwing; jobs, such as
carpentry or plumbing; or daily activities, such as lifting objects or
gardening.

Soreness or pain in the inner (medial) part of the elbow
may be
golfer's elbow. In children who participate in sports
that involve throwing, the same elbow pain may be described as
Little Leaguer's elbow.

Pinched nerves, such as ulnar nerve compression, which is the
pinching of the ulnar nerve near the elbow joint. This usually occurs with
repeated motions.

An
infection of the elbow may cause pain, redness,
swelling, warmth, fever, chills, pus, or swollen
lymph nodes in the armpit on that side of your body.
"Shooter's abscess" is an infection commonly seen in people who inject illegal
drugs into the veins of their arms.

Elbow injuries such as bruises, burns, fractures, cuts, or punctures may be caused by abuse. Suspect possible abuse when an injury cannot be explained or does not match the explanation, repeated injuries occur, or the explanations for the cause of the injury change.

Treatment for an elbow injury may include
first aid measures; application of a brace, splint, or cast;
physical therapy; medicines; and in some cases,
surgery. Treatment depends on:

The location, type, and severity of the
injury.

How long ago the injury occurred.

Your age,
health condition, and activities, such as work, sports, or hobbies.
